AQCUMULATOR.

Be itknown that I, Max SCHNEIDER, a subject of the German Emperor, and resifdentpof Radebeul, near Dresden, Germany, have invented certain new and useful Improvements in Accumulators, of which the vfollowing`- is a specification.

This in ention relates to improvements iii accumulated-s of which the positive ole electrode .consists of superposed lead lamellae which arefunnel-shaped, the common axle for said lamell being either solid or hollow.

The novelty of the invention consists in first,- that thecorresponding negative ole electrodeis shaped like a ring envelop w iichA ositive'one for the purpose of maintaining, besides saving room, an equal distance between the elec trodes at -all points; second, that said envelop does not form a closed but a split ring while it is uidedin fixed braces for the purpose of a 'Ording sufiicient room for its working; and third, that a plurality7 of electrodev airs are assembled in such-a 'way that the rst pair is inserted in the' hollow axle of the second pair and so on, for the pu`r ose of attaininv the greatest capacity in t e smallest possi leroom.

In theaccompanying drawing, Figures -1 and 3 are respectively, a diagrammatical cross section .and sectional elevation of the improved arrangement, while Fig. 2 shows in a diagrammatitail cross section the a s' semblage of several pairs oft electrodes, and Fig. 4 shows iii a fragmentary sectional View the construction of the single lamcll of the positive pole electrode.

The lamellar. a are subdivided by vertical slots b which run inthe direction of the diameters, fout' such slots being shown on the drawing though the number of the same may' vary according-to circumstances. By

this arrangement the following essential advantage is obtainedi-VVhen with the old arrangement the active material c. which lies between the lamellae. forms a closed rin it must tear upon its being extended, w iile with the new 4arrangement the material has efiicieut play to extend and besides a greater working surface is afforded b the slotting. The adjacent edges l tothe s ots'are some- 4 what bent up in order to inclose the single '/.oucs of themate'rial (Fig. 4).d l ecti'o e tie no'n- Around the ositi've c conducting enve op lz, with the ribs z is art e. The latter consisting o a late is, placed as a ring envelop e around t e positive elect-rode. This arrangementv-has the advantage that the two electrodes arekept equidistantat all points while much room specificati@ 0f team raient. v Patented 'lvebgg-iigmre 4, Application filed September 9, 1908.

ranred, over which lies the nflative elecissaved, the envelop'bein eapable'orl being'- put cl'ose. to the positive e ectrode, In order that the negative electrode mayhavesufii- B5 cient play to work, the envelop forming the same is not closed but is split at f. The envelop is not fixed at the bottom-but disposed loosely in the container, metal rin s g preferably fixed on the inner. walls o? tainer serving to hold the same iii place. l i lVith the im roved arrangementit is possible to assem le a plurality of electrode `airs in a very small space. As shown in ig. 3 the first pair of e in the hollow axle of the second air and -so lon, each negative pole electr e actingectrodes is inserted thereby' at vthe same time to the positive electrodes both outside and inside. f'

Y W'ith the above ldescribed arrangement an 8ol accumulator of extremely strong .power and takin tain Havin what I c 'aim and desire to secure by Letters the smallest 'possible room, .is obfully described my inventioinf withthe positive pole electrode consisting,

1. In an accumulator, the combination v of funnel-shaped. lead lamell and a common axle for the latter, ofthe negative pole 9o electrode consisting of split ring envelo arranged around'said gpofsitive electrode an metal rings around said fenvelop to hold the same in p ace, for the purpose set forth.

2. In an accumulator, in combinationa" 9b plurality of electrode pairs arranged within 5 each other and comprising each a positive'v consistingof'a split ring envelop arranged 'around said positive electrode, and. metal rings around said envelop to hold the same in lace, for the purpose set' forth.

n testimony whereof Ihave hereunto my hand in the presence of two subscribing-jv pole electrode consisting'of funnel-shaped ead lamellae and a common hollow axle` for the latter and a negative pole electrode 100
